Crouse-Hinds' porcelain lights were first released in the 1930's, with explosion proof lights designed for hazardous commercial applications. The EV series of lighting from Crouse-Hinds came with four shade options:RLM, Deep Bowl shades, Shallow Bowl shades and 30 Degree Angle. Type EVH Explosion Proof Lamps, came with a moulded rubber band, a clear globe furnished with a threaded ring and a aluminum cast guard. The dome, glass globe and bolts were built with enough strength to withstand any internal explosion, while the joints were tight enough to block any spark from escaping the fixture. Spaces between the lamp and wiring were sealed with explosion proof threaded joints.

Crouse-Hinds was originally founded in 1894 and its line of lighting products was widely recognized as one of the most durable lighting fixtures in the world. Crouse-Hinds was one of the major manufacturers of traffic signals and RLM warehouse lights that were commonly found around factories, auto shops and gas stations.

Many of these vintage barn lights that were nearly eradicated in the 1970's when many factories were forced to shut down due to EPA regulations. As factories and warehouses went out of business, they were renovated into lofts or torn down completely, leading to an ultimate destruction of many classic warehouse shades.
